13552	Backend now fails to start as master with a new database	bib1963	Klaas de Waal	"Git updated to today, 20200111.

New database created.

Set up with a single card, all settings at default.

Starting the backend brings up a line with:
2020-01-11 19:52:48.977164 N  MythBackend: Running as a slave backend.

Backend runs, however the frontend never connects.

I can see the DB traffic over lo for the FE.

When the BE starts, and doing a netstat, I see:
root@eth7 ~# netstat -anp | grep 6543

tcp        0      0 0.0.0.0:6543            0.0.0.0:*               LISTEN      17905/mythbackend  

tcp6       1      0 :::6543                 :::*                    LISTEN      17905/mythbackend

tcp6       0      0 ::1:45440               ::1:6543                TIME_WAIT   -   

tcp6       0      0 ::1:45444               ::1:6543                ESTABLISHED 17905/mythbackend

tcp6       0      0 ::1:45442               ::1:6543                TIME_WAIT   -

tcp6    3738      0 ::1:6543                ::1:45444               ESTABLISHED -


Notice the RX queue always has data in it and is never read.

This connection gets cleared down every 30 seconds with the backend giving out:

2020-01-11 19:58:36.249789 E  MythSocket(17cc960:92): ReadStringList: Error, timed out after 30000 ms.

2020-01-11 19:58:36.249831 W  MainServer: Unknown socket closing MythSocket(0x17cc960)

2020-01-11 19:58:37.245817 N  MainServer: Connected successfully

It's always the same response.


The Setup, does show the running system is supposed to be the master.

If I toggle the master/slave tick box, and going back in nothing changes, except that the tickbox is set to show the BE being the master.

No amount of changes to the General->Host Address Backend Setup makes any difference, Including listening on IPv4/IPv6/local/network interfaces, or changing it to a host name.

This was working, before I wiped the database, so I assume something changed a while ago and reference a database entry which was still existing, but is no longer inserted with a new setup.
